共に、成形型が高価になる欠点が存在した。(Prior art) In the conventional manufacturing method for skis in which the core is formed of foamed synthetic resin, a top material is placed at the top of the mold, and a bottom material is placed at the bottom of the mold. However, skis were manufactured by placing edge materials on both sides of this lower surface material and then integrally molding it with foamed synthetic resin.
However, in this ski manufacturing method, when the foamed synthetic resin is injected into the mold, the bottom material and edge material placed on the bottom surface of the mold may float up due to the foamed synthetic resin. Ta. Therefore, there was a manufacturing method in which a magnet was placed on the bottom surface of the mold to attract the edge material with magnetic force, and the edge material and bottom material were fixed to the bottom surface of the mold to prevent floating. Then, during use, the magnetic force of the magnet decreases and the edge material is not completely attracted.
The foamed synthetic resin leaks out to the lower surface of the edge material and the lower surface material, which requires time and effort in post-process finishing and has the disadvantage that the mold becomes expensive.

In the method of manufacturing skis by injecting and filling the inside with foamed synthetic resin, one end is inserted into the inner surface of the side mold, and the other end presses and supports the bottom material and the edge material. The present invention provides a method for manufacturing skis characterized by the provision of a pressing member.

After the ski is formed, the pressing material remains inside the side of the ski, so by making the color of this pressing material different from the color of the side of the ski, the color of the pressing material can be applied in a straight line on the side of the ski. Since it can be arranged, it has become possible to create a sense of fluidity. In addition, if duralumin or the like is used as the material for the pressing material remaining inside the side of the ski, it can become part of the ski's rigidity, and if glass fiber or the like is used, it can become part of the ski's reinforcing material. Furthermore, if a rubber material or the like is used, it can act as a vibration absorbing material.
